FLUSHING-VALVE FOR WATER-CLOSETS.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed December a, 1913. Serial macaw.

To all whom it may concern:

Beit known that I, Fnnncrs G. MERE- wn'rnnn, a citizen of the UnitedStates, residing at East Providence, in the county of Providence andState of Rhode Island, have invented certain new and useful Improvementsin Flushing-Valves for Water-Closets, of which the following is aspecification.

My invention relates to flushing valves for water-closets.

In valves of this character difiiculty has been experienced inpreventing leakin A valve consisting of a hollow rubber ba 1,cooperating with a valve seat on the flush pipe, has been found afteruse to become misshapen, and liable to non-registration in its seat whenthe latter has become rougher covered with a foreign substance, or whenthe surface of the rubber was somewhat rough, or the material somewhatnon-yielding. Gravity valves of solid rubber have also been tried, aswell as feather-edged valves consisting of a flexible annular flap, butneither of these have finished a continuously operative and successfulseal or closure.

It is the essential object of my invention to overcome the aboveenumerated. defects, and to provide a flushing valve that will under nocircumstances permit leaking; that shall be certain and simple inoperation;

and that shall be inexpensive to' construct and maintain.

A further object is to insure the sealing material against waste andescape. v

To the above ends primarily my invention consists in such parts and insuch combinations of parts as fall within the scope of the appendedclaims. I

In the accompanying drawings which form a part of this specification,Figure 1 is a side elevation of my flushing valve, showing the adjacentportions of the tank in vertical section, Fig. 2 a section on line a: wof Fig. 1 and, Fig. 3 a section of the valve and adjacent portion of thetank taken on a.

line corresponding with line y y in Fig. 2.

Like reference characters indicate like parts throughout the views.

In the drawings A represents the usual tank, in which is mounted thelower section B of the delivery pipe of which B is the upper section. Itwill be understood, however, that the sections B and B may if preferredconstitute a single pipe. In the present instance the pipe section B isprovided in its upper portion with an annular hollow extension b, inwhich is .mounted the vertical discharge pipe C. p In the presentinstance the lower end of the section B? has a threaded connection withthe portion 72 of the lower pipe section as at b. Upon the exterior ofthe upper section, near the bottom thereof is a vertically disposedreceptacle D, comprising an annular horizontal flange portion d, uponwhose outer margin is a vertical flange or Wall d; the wall, flange, andadjacent portion of the section B constituting a receptacle. Upon theupper end of the last mentioned section is an annular flange dpreferably downwardly inclined toward its margin. In the annularreceptacle D, is a mass of quicksilver E'. A valve member F has acylindrical body or side wall 7 and a top wall F,

the whole constituting a cylinder open at one end, like an invertedtumbler. This valve member is adapted to move or reciprocate vertically,and when in closed position it surrounds the major portion of thesection B and has its lower extremity immersed in the quick silverresting upon the bottom portion 03 of the receptacle D, which portionall forms the valve seat. The flange 03 which is contiguous to or incontact with the inner face of the valve member F, incidentally servesto some extent as a guide to the vertical movement of the member F, butthis flange is essentially purposed to prevent the escape of thequicksilver E over and through the top of the pipe section after thevalve has been lifted and the water in the tank has begun to flowthrough the pipe sect1ons.

It is convenient but not essential that a special guiding means beemployed for controlling the valve member F in its vertical travel. Oneconvenient means for this purpose comprises two brackets Gone above theother, comprising loops 9 which embrace the pipe C, and loops 9 in thesame plane and connected with the loops 9. The larger loops gr beingconnected by spaced vertical rods g Since the loops 9 are of slightlygreater diameter than the diameter of the valve member F, the guide rods9 serve to loosely confine the valve member in a vertical path. It willbe understood that the described guiding means is not exclusive but thatthe valve may be guided in any usual well-known manner.

The valve may be raised or lowered with relation to its seat by any ofthe customary means. In the present instance the means employedcomprises a two-arm lever H, having a horizontal portion 7:. and avertical portion 72.; the latter being mounted on a pivot pin 2' in earsI upon the plate J fixed to the upper portion of the tank a.

A rod K with an operating handle lc is slidably mounted in the tank Awith its end in contact with the depending portion h of the lever H, andoperates in the usual well-known way to elevate the valve member Fthrough a member L which connects the outer end of the portion h of thelever H with a ring Z attached to a stud Z, whose threaded shank Zengages the member F with the assistance of a nut Z. The member L in thepresent instance is a flexible member or chain, but may if preferredconsist of a rod. The method of connecting the end of the member L withthe valve member is not of essence to the invention, but when the lattermember is composed of glass, as is preferred, the described means ofconnection is highly advantageous. Not only is the valve member F madeof glass, but the pipe section B, and the receptacle D is in the presentinstance also of glass, since that material has been found to be moredurable, not subject to corrosion, nor other influences which haveheretofore interfered with the perfect operation of the valve andlessened the period of its use.

The described valve, valve seat or receptacle, and sealing agent, are socorrelated that a perfect seal is assured, regardless of whether thevalve approaches its seat uniformly at the same point or at varyingpoints, and in any event the quick silver performs the sealing functionsefficiently.

What I claim is,

1. In a flushing apparatus for water closets, the combination with thetank, of a delivery pipe mounted in the tank, a receptacle upon anintermediate portion of the pipe comprising a horizontal flange, and avertical flange upon the last mentioned flange, a mass of quicksilverupon the horizontal flange intermediate the pipe and the verticalflange, a downwardly incllned guard flange upon the end of the pipeextending above the horizontal flange, and a hollow valve membersurrounding the pipe and guard flange and seated in the mass ofquicksilver.

2. In a flushing apparatus for water closets, the combination with thetank of a delivery pipe comprising two vertical sections, one of saidsections being fixed in the tank, the second section being detachablyengaged to the first section withinthe tank and composed of glass, anupwardly directed receptacle integral with the lower portion of thesecond section, a mass of quicksilver in the receptacle, a guard flangeupon the upper open end of the second section, and a cup shaped valvemember inclosing the second section and resting upon the receptaclewithin the quicksilver.

Y 3. In a flushing apparatus for water closets, the combination with thetank, of a delivery pipe mounted in the tank, a branch delivery pipeupon the first pipe and parallel therewith, a receptacle upon thedelivery pipe, a mass of quicksilver in the receptacle, a guardflangeupon the delivery pipe .overhanging the receptacle, a verticalguideframe upon the branch pipe whose lower portion incloses thedelivery pipe above the receptacle a cup shaped reciprocating valve inthe frame movable into and away from the mass of quicksilver, avibratory lever pivotally mounted on the tank above the valve member, amember connecting the lever and valve member, and means on the tank forvibrating the lever.

In testimony whereof I have affixed my signature in presence of twowitnesses.
